I was prescribed Amitriptyline for stomach/chest pain and for a short while it worked well enough (although I still had a little pain). My dose was increased from 10 mg to 50mg. However, the more severe pains have returned. After seeing the doctor yesterday he told me to stop taking the Amitriptyline and prescribed me with Citalopram (20mg) to take instead. Has anyone had or have taken this tablet and found it helpful for pain?
